Raspberry Pi 3 To Get ARM TrustZone Support with Linaro OP-TEE Port

Orange Pi Development Boards

If you ever wanted to experiment with ARM Trustzone, and IoT security, you’ll soon be able to do so with the Raspberry Pi 3 board thanks to a port of Linaro OP-TEE (Open Portable Trusted Environment Execution) by Sequitur Labs.

OP-TEE Architecture
OP-TEE Architecture: optee_client, optee_linuxdriver and optee_os

Broadcom BCM2737 SoC found in Raspberry Pi 3 board already had TrustZone hardware for isolation and protection for sensitive material such as cryptographic keys, algorithms and data, but the upcoming software release will mean the feature can now be used, and it’s free for trial/evaluation, and  education. Trustzone is also used for DRM (digital rights management), but in the case of Raspberry Pi 3 it will most likely used to teach how to secure the Internet of Things (IoT).

The release is scheduled for July 11, with source code and documentation to be available in OP-TEE github account. All you’ll need to get started is a Raspberry Pi 3 board, a micro SD  card to load, a Bus blaster, a custom cable to enable bare metal debugging,  a single firmware image with 64-bit Linux, ARM Trusted Firmware, and OP-TEE image, OpenOCD and the configuration file for the Raspberry Pi 3, as well as some code samples and a quick start guide.

Support for OP-TEE will be provided through forums on Linaro.

You may find a few more details in the press release.
